Application filed January 24, 1914. Serial No. 814,170.

To all whom it may concern:

Be it known that I, EMANUEL RIoKnRs- BERG, a citizen of the UnitedStates, residing at Cleveland, in the county of Guyahoga and State ofOhio, have invented certain new and useful Improvements in Self-ClosingFaucets; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the artto which,

j with anintervening D washer which form it pertains to make and use thesame.

This invention relates to self closing faucets and consists in thepeculiar construction of the same allowing of the convenient adjustmentor regulation of the valve and its seat in relation to each other, saidregulation being accomplished by means of an adjusting device located atthe upper end of the valve stem which adjusting device comprises meansfor locking the stem in the adjusted position.

This invention further consists in the combination of valve adjustingmeans, and operating means with means for preventing the rotation of thevalve and valve stem when it is adjusted or when it is opened or closed.

The object of this invention is to produce, first, a faucet of the typeset forth which can easily and economicallybe manufactured and then, toproduce a faucet in which the valve and its seat do not become wornunnecessarily by working on each other.

Another object of this invention is to produce a faucet which willpreventthe usual pounding or rattling when the valve is open.

.Gther objects are apparent and will appear in the specifications and befully set forth and claimed.

In the drawings, Figure I, is aview in central vertical section of afaucet embodying this invention, Fig. II, is a view in front elevationwith a portion of the cap and body removed showing the means employedfor opening and closing the valve. Fig. III, is a top plan view of thefaucet. Fig. IV, illustrates in section the valve stem and partscontiguous thereto, showing the'means employed for preventing therotation of the valve stem while at the same time allowing it freevertical movement. Fig. V, is a sectional view of the valve stem and itscontiguous parts showing a modification of the means shown in Fig. IV.Fig. VI, illustrates in elevation a valve stem constructed in crosssection similar to that illustrated in cross section in Fig. IV, showingthe same as provided with the side splines which engage 111 slots orways in a contiguous part or member of the faucet. Fig. VII, is a viewin elevation of a valve stem made in accordance with the cross sectionalview in Fig. V. showing the lower portion of the stem formed polygonalin cross section and adapted to have vertical movement in acorrespondingly shaped soclret forming part of the faucet. Fig. VIII,illustrates a lower and upper nut the means for adjusting the valvestemand valve hence the tension of the compression spring and also formsthemeans for locking theadjustment,the upper'nut acting as a lock nutwhich is forced tightly against the D shaped washer. Fig. IX, is adetailed view of the packing box bushing which is provided with thecollar shown in Fig. X.

In the drawings, 1 represents the main casing of the faucet whichisprovided with j the usual; spout 2 and valve seat 3..

4 represents the valve stem having valve 5 located on the lower end,said valve being of any suitable material and adapted to'seat itself onthe'valve seat 3 of the faucet is held normally in said seat by means ofa compression spring 6, the lower part of said spring resting againstthe annular shoulder enlargement? of the valve stem 4 and the upper endof said spring 6 resting against a ring 8' which surrounds the lowerpart of the collar 8. The collar 8 is provided on its upper. end withscrew threads and forms a packing box while the lower end of said collar'8 is provided with a depending slotted flange said slots of theflange forming ways 9, 9, which receive the splines 10, 10 of the stem 4thus preventing the-valve stem from rotating when the parts areassembled and at the same time allowing the limiting of the upward throwof the valve stem 4 and i the valve 5.

By screw threading the upper portion of the collar 8 is fitted thusforming the stuffing box around the stem 4, and it is this bushing alsowhich rests upon the upper edge 13 of the faucet body and is clampedthereon by means of the cap let. The upper end of the bushing 12 isprovided with a suitable number of oppositely inclined ways 15 whichreceive and form the lower support and runs for a series of balls 16 andwhich in conjunction with a bushing 17 having correspondingly shapedruns on its under surface form the means for opening the valve of thefaucet upon the rotation of the bushing 17. The valve stem beingscrewthreaded on its upper end is engaged by an adjusting nut 18 whichrests upon. the upper end 19 of the bushing 17, thus adjusting of thevalve in relation to seat 3 is accomplished by the turning of this nut18, the spring 6 holding the valve 5 to the seat 3 when the faucet is inits normal position. Above the nut 18 is a D shaped washer 20 which fitsover the end of the stem l, the stem at this portion being flattened .toaccommodate the D washer. Above D washer 20 is a lock nut 21 which bybeing screwed down upon the D washer 20, locks the parts in properadjustment. The upper end of the bushing 17 is formed polygonal and thisportion fits into the handle cap 22 which has a correspondingly shapedorifice. The handle 22 is kept in place by means of the indicator nut 23which is screw threaded to the extreme upper portion of the stem 4. lihehandle cap 22 is formed with a downwardly depending flange 24: whichfits over the clamping cap 1-1 thus preventing the accumulation offoreign matter in the working parts of the faucet.

In Figs. I, IV, and VI, I have shown the valve stem as provided with twosplines 10,

10 which are guided in ways 9, 9 in the contiguous part of the faucet toprevent the turning of the stem thus causing a perfect vertical movementto the stem in relation to the seat 3.

By referring to Figs. V, and VII, it will be seen that I have shown amodification of the the spline construction and in place of the splinesI have illustrated the lower portion of the valve stem 4 being formedpolygonal and have at the same time formed the contiguous part of thefaucet so as to correspond with the stem 1 thus obtaining the sameresults as are obtained by the spline construction shown in the otherVleVS- By referring to Fig. I, it will be seen that I have soconstructed this invention that if it is desired to replace the valve 5all that is necessary to do is to remove the cap 14:

and the whole working parts of the faucet may be placed in any radialposition deired.

In setting forth this invention I have shown and described it as itappears best adapted at the present time but there are details ofconstruction which can be easily changed without departing from thisinvention hence I do not wish to be limited to the exact construction asset forth.

hat I claim is:

In a self closing faucet, a valve, a valve stem, a rotatable handle,means operated by said handle to lift said valve and stem, adjustingmeans at the upper end of said stem for adjusting the parts, saidadjusting means comprising an adjusting nut and a locking nut with anon-rotatable washer located between said nuts.
